iTunes

I have several ipods; a nano (old version), a shuffle and a ipod (big white one original)...

Anyway, I just purchased a new imac a few weeks ago and I cannot for the life of me get but one of them (the shuffle) to be recognized on it. I hook them up separately, through different usb connections etc (basically I've tried everthing) to get the iMac to locate the other ipods and nothing works.
